Standard

OSS Standard storage provides highly reliable, highly available, and high-performance object storage service that supports frequent data access. The high throughput and low latency of OSS make it well suited for storing social networking content such as images, audio, and video. It is also great for storing large unstructured data sets for use in big data analytics.

OSS Standard storage has the following features:

Designed for 99.999999999% (11 nines) durability.

Designed for 99.99% availability.

High-throughput and low-latency access performance.

Supports HTTPS.

Supports Image Processing.

Infrequent Access

OSS Infrequent Access storage is suitable for storing long-lived, but less-frequently accessed data (once or twice per month). With a storage unit price lower than the Standard class, it is suitable for longer-term backup of various mobile apps, smart device data, and enterprise data. Objects of the Infrequent Access storage class have a minimum storage duration. Charges apply if you delete objects that have been stored for less than 30 days. Objects of the Infrequent Access storage class have a minimum billable size. Objects smaller than 64 KB are charged as 64 KB. Data retrieval incurs charges.

Archive

OSS Archive storage has the lowest price among the three storage classes. It is suitable for storing archival data for a long time (more than half a year recommended), such as medical images, scientific materials, and video footages. The data is infrequently accessed during the storage period and it may take about one minute to restore the data to a readable state. Objects of the Archive storage class have a minimum storage duration. Charges apply if you delete objects that are stored for less than 60 days. Objects of the Archive storage class have a minimum billable size. Objects smaller than 64 KB are charged as 64 KB. Data retrieval incurs charges.
